Self-organizing maps classification with application to the low-frequency magnetic field emitted by portable computers

Abstract

This study presents an application of the Self-Organizing-Map method used for the classification of the extremely low-frequency magnetic field emission in the close neighborhood of the portable computers. The experiment is conducted on two different groups of portable computers: (i) laptop and (ii) tablet computers. After measuring their extremely low-frequency magnetic field emission, the Self-Organizing-Map is used for the classification of these results, which authorized the typical emission levels. Some of them are dangerous, because they are far above the valid safety standards' limit. At the end, a discussion is performed on the importance of using the classification as a possible solution for safely use of the portable computers. In this way, it is used to define and reduce the risk of the magnetic field emission negative effects to the portable computer users.
